Only on architecture, PowerPC, is in bad enough shape to require one
image for actual booting (when possible at all) and other one to
supply the kernel to dbootstrap.
Wouldn't it be easier to just get the kernel directly from one of the
'linux' files lying around, in the case that the user is installing by
a method other than floppies? This might be an easy, general fix we
can do for all arches.

Well, you would now about that more than I...

That's not a bad name for it... It also has a boot loader, and, on
some arches, some documentation and stuff.

Some things about the documentation is indeed evil, but I still think
it was the right idea to do it that way. I would love it if there a
"quick start" mode -- that could be added to the front of the
documentation easily. And you can cross-link into the full

Some of the steps are rather different, but SGML has facilities for
blocking off areas as one arch only.
It's pretty easy to just chop around whole sections (although you have
to make sure that any references to those sections are conditionalized
out as well).

Well, I don't think this necessarily reflects on the documentation but
rather on the lack of strong documenters, who know what they are doing
with document maintenance issues, putting out leadership and getting
I mean, you could easily have a completely gut install-methods.sgml
and have install-methods-powerpc.sgml (if that's really the right
thing to do, if there is really so little commonality), so long as
they both have sections with the same IDs in them.
I guess my conclusions are a bit different. Some things, such as
laying out files on a TFTP server, for instance, are remarkably
identical across architectures, and decided not i386-centric.
Yet that is barely documented at all.
My conclusion is not that the 'one size fits all' is to blame, because
if that was true, we'd see the more common stuff documented better and
the wierd arch stuff not documented well.
In fact, what we have is very limited involvement by
porter/documenters. I pretty much conclude there is no such thing as

Fine, but as I said above, you can do all that in the current
documentation just as easily (easier?) that doing it from scratch.

I don't disagree that some structural changes would have to be made to
the main documentation to facilitate this. Better layout and break-up
of files to make it clear for porters with not much time where to edit
stuff, focusing on the points of divergance.
My point is that this can be done in the main SGML file, without
spinning off a bunch of little ASCII files.
